Abstract

A circuit for processing radio frequency signals. The circuit includes a substrate where the circuit can be placed. The substrate can be a meta-material and can incorporate at least one substrate layer. A four port circuit and at least one ground can be coupled to the substrate. The substrate layer can include a first region with a first set of substrate properties and a second region with a second set of substrate properties. Substrate properties can include permittivity and permeability. A substantial portion of the four port circuit can be coupled to the second region. The permittivity and/or permeability of the second region can be higher than the permittivity and/or permeability of the first region. The increased permittivities and/or permeabilities can reduce a size of the four port circuit and effect a change in a variety of electrical characteristics associated with the four port circuit.
